When I try to query a property that is a nullable enumeration (Nullable<ItemStatus>) via ICriteria I get a FormatException (nested inside an ADOException).
Neither the Linq version nor the ICreteria version work. Oddly enough, if I use dynamic linq (should be included in the orcas beta) it works just fine.
